Hi,
I have just updated previously announced
and uploaded to
http://people.freenet.de/AiTI-IT/Python/Console.py
version
of Console.py because I was not satisfied with
it (it didn't support arbitrary ANSI escape
sequences for setting text colors ...)
Now the Console() class supports ANSI escape
sequences of the form ESC[#m and ESC[#,#m ,
so it is possible to set any colors for text and
background via escape sequences.
Resetting the colors with ESC[0m will set
them back to initial(default) ones.
Now it is also possible to send a _sequence_
of ANSI escape sequences to Console.write().
e.g.
'\x1B[31m'
'\x1B[1m'
will cause later submitted text to be light red.
Running Console.py creates coloured
test output which can be checked for
integrity.
Any feedback is welcome.
